I remember one nugget of info in the original thread, and it was Raistmer saying that as long as (or especially if?) the chips become OpenCL capable it'll make more sense. To that I remember replying that "Bruce Wayne" Tegra (Tegra 4) was rumored to be OpenCL. For some reason the Wikipedia page I had linked to has no mention of OpenCL for Tegra 4 anymore, but the grapevine is buzzing:

" ...the high-end version of Tegra 4 will bring 72 cores in the GeForce GPU, without disclosing if the cores in question support CUDA or not. Remember that two years ago, Nvidia mentioned that their T40-class hardware will be fully compliant with the OpenCL and CUDA, and based on the Kepler architecture, which wasn't even announced at the time."

I didnt have a smart phone for that old thread but I do now. I still think it will be just a novelty. I left a app running by accident when i put the phone on the charger. It got hot as heck and never did charge the battery. Until the processors get a lot better and battery life is improved I dont see large scale crunching. And I would not do any on a phone anyway. Thats not why I have smart phone. [/quote]

While smartphone crunching is technically possible I doubt that it is a practical proposition due to the amount of processing required to cope with a work unit and the limited battery life of a smartphone.Bob Smith

LOL, yeah. When I see how quickly the battery of my Samsung gets zapped by just playing a 3D Tetris clone, or Angry Birds, I don't even want to crunch anything on it. 20 minutes of game play and a fully charged battery --coming off the USB wire-- is at 55%. Jord

Seriously smartphones sitting on desks not in bag/pockets/cars might be a way of capturing data on larger quakes. But if you didn't feel it,it wasn't a quake...Bob Smith

For the forseeable future it's pretty much a given that when smartphone/tablet crunching takes off, it'll only make sense to do so when charging the device. My only gripe with this (theoretical ATM) scenario is that these devices have integrated batteries (to help make the devices slimmer I guess). And batteries dislike heat...

I don't know if I'd be willing to fry my battery for the sake of a little bonus crunching. However if I had a device that made it semi-easy to pull out the battery (like my current dumb-phone) I'd probably make the extra effort.

A retired smartphone/tablet I'd probably leave plugged in and crunching 24/7 but that scenario is 4-5 years away, for me at least.

PS @ML1 I wonder if Quake Catcher is doable on such a highly mobile device. If it is I'd most definately run it, especially in Greece.

Bear in mind that a computer's USB port only provides a maximum of 500mA. If you have a wall charger for the phone, it's probably capable of supplying more current and will keep the battery charged. If the phone didn't come with one, some bluetooth devices do. A car charger also supplies enough juice.

As for heat, my phone has been overheating for almost a year just while doing things it's supposed to be able to do, sometimes even with its display off. If really necessary, I either blow cool air at it or take the back off and *carefully* dab water all over the battery. It's amazing how quickly it evaporates. Removing the battery to protect it from the heat is not an option; the phone shuts off without it, even when plugged in.DavidSitting on my butt while others boldly go,

Milkyway for example, see this thread. PrimeGrid runs fine AFAIK and WUProp runs also on Android and that gives us a short list of projects that run on ARM/Android.

I ran some Milkyway & Primegrid on my phone when I first tested the client a while back. I didn't have any issues with my old MyTouch 3G Slide. Looking further into that stats list the project SubsetSum@Home looks to be the one cranking out the highest RAC for these devices, or the users are dedicating most of their time to that project for these devices.SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the BP6/VP6 User Group today!

Note that by its specification USB 3.0 ports can supply up to 900 mA when transferring data, and 1.5 A when in "battery charge" mode.

The current battery charge specification states 5A as the maximum. However the specification sheets for Molex's micro USB connectors state they have a maximum capacity of 1.8A. Which is also the maximum capacity stated in the old Battery Charging Specification from '07.SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the BP6/VP6 User Group today!
